It's interesting that I no longer see that read option photo at 49ers.com. And yes to a previous poster, I know the Pistol is a formation. From what I saw in the photo, that was certainly a read option, and it looked like Pistol to me as well. No surprise.
I guess they saw my post and removed the photo from the site?
There were a few other photos of the offense that are gone now too. At least the photo is still in the history.
